You need to do a serious business analysis…
First, realize that your mainstay of group classes only happen at night after working hours.
People tend to NOT come to classes on Friday, Sunday, and some are very picky about Saturday - you need to know what times work for people.
So, with a Mon-Thur - 4 evenings a week for major classes.
Now you have to figure in what time classes can start.
20 years ago in my city, you could start classes around 6 PM - people could make it by then from work…
Now, it is closer to 7 PM. Now you CAN do kids classes earlier. So you have to determine what a workable class schedule is
In reality, you have time for a maximum of 2 adult classes in an evening and at that you are teaching until 9 or 9:30.
The next group is kids. They are in school until 4 so you can have a kids class that begins around 4:30 PM until 5:30 or 6. If you do the thing of a bus and pick them up from school, you can charge more and increase students…but you have the insurance expense and the expense of a van.
Daytime…you can only get those that don’t work - retirees, housewives, people that work nights… Limited population.
You have to be able to teach something they can do like Taijiquan.
Add all of that together and you get a maximum number of class hours per week.
Now you have rent, utilities, phone, advertising, and INSURANCE (trust me, you need insurance).
You also have to consider the space you have…
If you do the math and need an average of 20 people in a class…but your facility is crowded with 15, you will fail from the beginning.
You should NEVER count in private lessons in your calcualations on income. Those are for more money but they should be considered extra…something you can’t depend on.
When you do all of the financials and - if you still want to do it, you then have to decide how you handle payment - contracts or none, refund policies, etc…
You have to keep the business aspect completely separate from the teaching aspect. Quality of teaching has nothing to do with whether or not a person paid their fees…
Finally, the realities of the world is that you pretty much have to have an easy class and then a die hard class to stay open. You can’t be commercially viable teaching everyone like they will be inheritors of the style.
It is VERY difficult to make big money teaching.
